1. FATORES DE EMISSÃO E DE ENRIQUECIMENTO DA CROSTA PARA ELEMENTOS TRAÇO (MP2,5) EMITIDOS PELA FROTA VEICULAR NA REGIÃO METROPOLITANA DE SÃO PAULO, BRASIL
Air pollution can cause several negative impacts on health and the environment. In large urban centers, this pollution is directly related to anthropogenic activities, mainly activities in the transportation sector. This study analyzed data on black carbon, fine particulate material (PM2.5) and its main trace elements from automotive vehicles (S, P, K, V, Cr

3. Storage of purified biogas (biomethane) at low pressure
ABSTRACT The global use of fossil energy sources has led to the need to develop technologies capable of mitigating its consequences. One such option is anaerobic biodigestion, which is already scientifically well-established, although the use of its main products (biogas and biomethane) still requires further development before they can be employed in automo

4. Water Diffusion in Double Cantilever Beam Adhesive Joints
Abstract Structural adhesives are increasingly being used in the aerospace and automotive industries. They allow for light weight vehicles, fuel savings and reduced emissions. However, the environmental degradation of adhesive joints is a major setback in its wide implementation. Moisture degradation of adhesive joints includes plasticization, attacking of t

5. Perspectivas para a contribuição do uso do etanol no transporte público urbano, visando à redução da poluição atmosférica - estudo de caso: Projeto Best / Perspectives to the contribution of ethanol utilization in the public urban transport, aiming to reduce air pollution - Case study: BEST Project
Diesel oil is the fuel with major importance in the automotive energy matrix in Brazil, corresponding to nearly half of the total fuel volume consumed in the country, apart from being a global option fuel for public urban transport. Diesel oil is a fossil fuel, not renewable, produced from fractioned petrol distillation; its use is linked to local air pollut

6. Introdução de misturas de GNV e hidrogênio (Hidrano) em veículos convencionais no Brasil e seus impactos econômicos, ambientais e energéticos / Introduction of CNG and hydrogen (HCNG) for conventional vehicles and its economic, environmental and energy impacts
Several strategies have been proposed to introduce hydrogen in the economy specifically in the transport sector in order to reduce environmental impacts of conventional fuels. One of the strategies implies in adding hydrogen to compressed natural gas (HCNG), making use of the existing refueling stations and natural gas fleet. Thus the costs and time for the

9. Polyurethane structural adhesives applied in automotive composite joints
In recent years structural adhesives technology has demonstrated great potential for application due to its capacity to transform complex structures into solid unitary and monolithic assemblies using different materials. Thus, seams or joints integrate these structures providing, besides a reduction in weight, a considerable increase in the mechanical resist

10. Influência da adoção do carro flex fuel na estratégia competitiva dos distribuidores de combustíveis / Influence of the adoption of flex fuel vehicles in competitive strategy of fuel distribution industry
The fuel distribution environment has been facing drastic changes in Brazil in the past years. This fact may be affirmed after having carried out an environmental analysis through the employment of a model proposed by Almeida (2010). This analysis also allows one to assert that the environment of fuel distribution has been turning into what D\ aveni (1995) d
